l GARBAGE. INCINERATOR.

Application led April 5,

T0 all whom z' may concern.:

Be it known that we, THOMAS TREGAN- owAN and LEO PAUL OHARA, citizens of the United States, residing at Pittsburgh, in the countyA of Allegheny and State of Pennsylvania, have invented cert-ain new andnseful Improvements in Garbage Incinerators, of which the following is a specitication. I

This invention relates to certain new and useful improvements in incinerators for burning garbage and other refuse of a household or building and has particular reference to that type of incinerator capable of installation in the kitchen of a house or in the kitchen of the different apartments of an apartment house, whereby the garbage or refuse may be burned by the occupant of an apartment.

The primary object of the invention embodies in an incinerator of the type above constructing the incinerator or furnace of comparatively few structural elements that are capable of being replaced should damage or injury occur thereto.

The invention further includes the installation of individual ineinerators in the kitchens of apartment houses with a sinele vertical flue aligned with a plurality of 1ncinerators, providing a' draught and a single exit or discharge passage for the ashes.

A further object of the invention resides in the provision of an incinerator of the type above set forth -wherein the incinerator casing or body portion is formed of' fire brick and enclosed by a metal casing housing spaced therefrom to provide a non-conducting heat space between the fire brick wall and casing.

iWith the abo-ve general objects in view and others that will appear' as the nature of the invention is better understood, lthe same consists in the novel construction, combination and arrangement of parts here- -inafter'more fully described, illustrated in the accompanying drawings and pointed out in the appended claims. y

In the drawings forming a part of this application and 1n which like designating characters refer to corresponding parts throughout the several views,

Figure 1 is a frontelevational view of an incinerator constructed in accordance with the present invention, showin the reeeiving door for the refuse, the oor. for

Figure 3 is a vertical section view taken at right angles to the form shown 1n Figure 2, showing the inclined side grates, the

wedge-shaped baffle and the burner tubes supporting the inclined grates with the ashpan disposed beneath the grate.

Figure 4 is a. -horizontal sectional view taken above the wedge-shaped lbaffle shown in Figure 3, illustrating'the inclined side grates and thel perforated batlie.

Figure 5 isa detail sectional view showing angle bar mounting for onev end of thi,l 4pivoted grate, and the burner tubes, an

Figure 6 is a detail sectional view showing the incinerator installed in the kitchen wall of an apartment kitchen with the fiue associated therewith extending to the lower apartments and the ground floor.

Referring more indetail to the accompanying drawings and particularly to Figures 1 to 5, there is illustrated an incinerator to be placed in the basement of a building to receive garbage or other refuse, through a feeding flue, while in Figure 6 of the drawings, the incinerator is shown as installed within the kitchen of an a artment. with the bottom wall thereof either provided with an ash-pan or an opening, to permit the collection or discharge of the ashes within the flue. In .theincinerator shown in Figures 1 to 5, the same embodies side and top walls 1 and 2, formed of lfirebrick, the same being supported on a basewall'3, carrying mounting feet 4. The firebrick casing is surrounded by a metal housing 5, spaced therefrom by members 6 to provide an intervening air-space 7 constituting a non-'conductor for heat resulting from the operation of the device. As shown walll 2 of the tire-brick and the casing 5, is provided with'an opening 8 to smoke and fumes and a opening when the incineratoris installed in the basement of abuildin The front wall of t e incinerator as shown in Figure 1 is provided withv a refusereceivingk opening closed by a door 9, the

ermlt the escape of` so to provide a feed 'the jet openings angle iron 12 bottom wall 3 supporting an ash-pan or receptacle 10 accessible by the `ash-door 1l as illustrated.

The burners and grate elements contained within the incinerator include a mounting shown more clearly in Figures 2 and 5, the. same-being ot' H-formation and supporting the stud end 153 of the pivoted grate 14, the opposite endjthereof carrying a rod 15 projecting through the front wall of the incinerator. casing as shown in Figures 1 and 2, for the application of an operating key or handle 16, the

rate 14 being disposed between vthe receiving opening and the ash-compartment of the incinerator, As shown in Figure Il, a

.strap iron 17 supports the forward end of the grate in addition to the front wall of the incinerator.

A pair of inclined side grates 1S having the upper ends thereof engaging the opposide side walls of the incnerator are provided upon the lower ends with brackets lf) that rest upon burner tubes 20 fas clearly shown in Figures 3 and 5 with the lower ends 18 of the inclined gratos projecting inwardly of the burner tubes and overlying 20 t0 protect the lnirners from ashes or other refuse falling thereon and clogging the. jets. The burner tubes 20 are supported in socket portions 12 provided in the channel brace '12, while the opposite ends of the burner tubes are, snpported in the strap bearing 17.

As shown more clearly in Figures 1 and 2, a gas supply pipe 21 is supported exteriorly of the front wall oIAhe incineratorvl and has valve connections 22 with the burner tubes 20.

A. wedge-shaped baille is disposed between the lower ends of the inclined, side trates 1S, the same having perpendicular endfwalls 23 and inclined perforated side walls 24 with the adjacent edges of the end walls'23 serrated for an interlocking engagement, the rear ends of the side walls 24 carrying pins 25 for pivotal mounting in the channel brace 12 while pins carried by the opposite ends of' the side walls 24 are supported in brackets 26 adjacent theV strap bearings 17.

From the above detailed description of the device it is believed that the construction and operation thereof Will-at once be apparent, it being noted that the incnerator is of extremely simple construction, the few parts united to constitute an operative deout necessitating the employment lof skilled labor. Y

lVhen the incinerator is installed in the basement of a building, the opening 8 1n the upper end thereof communicates with an outlet flue and garbage o: other refuse is introduced through the door opening 9, the @eine falling upon the perforated wedgeforms, modilications vicebeing easily and quickly replaced with-v shaped baffle for reception of theinclined side gratcs 18. 'lhe burner tubes 2() are suitabl)Y ignited, and the jets issuing therefrom will bedirected inwardly of the wedge-shaped baille to escape through the perforations therein and eiliciently burn the refuse, the ashes falling through the grates and into the pan 10 at the lower -end of the inc-inerator. The grate 14 may be shifted to discharge any ashes that might collect thereon, while the smoke andfumes from the incinerator. will escape through the opening 8 at the upper end thereof and into the flue.

The incinerator is illustrated in Figure G as installed in the wall of a kitchen in an apartment or other house, the 'wall being designated by the numeral 27 having a flue passage 28 therein with the incinerator entirely disposed within the flue with the. front wall thereof being substantially Hush with tbe face of-the kitchen wall. In installations ofthis character, an opening may be provided in the vbottom wall of the incinerator, and the ashes permitted to fall therefrom and be removed through the side opening 29 at thelower end of the flue.

VVlle the form of the invention herein shown and described is what is believed to be the preferred embodiment thereof, it is nevertheless to be understood that various and arrangements of the parts may be made without departing' from the spirit .and scope of the invention as claimed.

IVhat we claim as new and desire to secure by Letters Patent, is
